“There’s a great parallel that they draw between my character and Tony Stark,” said Evans, who returns as the patriotic Avenger Captain America. “It’s something we can all relate to in terms of how we perceive our own society and culture, in terms of what is best for people. You can go right down to Democrat and Republican; everyone has a different opinion of what’s best.”

The film will detail the fallout following the introduction of the Sokovia Accords, a document proposing that superheroes be held accountable for the damage they cause during their world-saving endeavors.

“You have this team of people who are destroying every city they go to, but they’re saving the world,” said Evans, possibly referring to the incident in Sokovia depicted in “Avengers: Age of Ultron.” “So it’s a matter of, do we monitor these people or do we let them monitor themselves? The beautiful thing with ‘Civil War’ is that no one’s right and no one’s wrong; it’s just your personal opinion.”

The film will pit Captain America against Iron Man when the latter comes down, surprisingly, on the side of accountability. Robert Downey Jr.’s armored Avenger previously bucked supervision in “Iron Man 2,” but his opinions have changed over the years.

“We’re going to have a nice evolution where you have a guy like Cap, who grew up with structure — he was a soldier and he liked hierarchy, he liked the chain of command. Now, all of a sudden, you have a guy who used to love the system not so sure about trusting it. And a guy like Tony Stark, who used to buck the system and dance to the beat of his own drum all of a sudden thinking, maybe we need some order.”
